入选标准

  • 1) Age 18-80 years, inclusive
  • 2) Objectively confirmed acute PE, based on CTPA showing a filling defect in at
  • least one main or proximal lobar pulmonary artery (PA)
  • 3) Elevated risk of early death/hemodynamic collapse, indicated by at least two
  • of the following new-onset clinical criteria:
  • i) Electrocardiogram (ECG)-documented tachycardia with heart rate >= 100 beats
  • per minute, not due to hypovolemia, arrhythmia, or sepsis;
  • ii) SBP <= 110 mm Hg for at least 15 minutes;
  • iii) respiratory rate > 20 x min-1 or oxygen saturation on pulse oximetry
  • (SpO2) < 90% (or partial arterial oxygen pressure < 60 mmHg) at rest while
  • breathing room air;
  • 4) Right-to-left ventricular (RV/LV) diameter ratio >= 1.0 on CTPA
  • 5) Serum troponin I or T levels above the upper limit of normal
  • 6) Signed informed consent

排除标准

  • 1) Hemodynamic instability*, i.e. at least one of the following present:
  • a) cardiac arrest or need for cardiopulmonary resuscitation;
  • b) need for ECMO, or ECMO initiated before randomization;
  • c) PE-related shock, defined as: (i) SBP < 90 mmHg, or vasopressors required to
  • SBP >= 90 mmHg, despite an adequate volume status; and (ii) end-organ
  • hypoperfusion (altered mental status; oliguria/anuria; increased serum lactate);
  • d) isolated persistent hypotension (SBP < 90 mmHg, or a systolic pressure drop
  • least 40 mmHg for at least 15 minutes), not caused by new-onset arrhythmia,
  • hypovolemia, or sepsis.
  • * Patients who presented with temporary need for fluid resuscitation and/or
  • catecholamines may be included, provided that they could be stabilized within 2
  • of admission and maintain SBP of >= 90 mmHg and adequate organ perfusion without
  • catecholamine infusion.
  • 2) Need for admission to an intensive care unit for a reason other than the
  • index PE episode.
  • Note: Patients who test positive for SARS-CoV-2 can be enrolled where the
  • investigator
  • believes that the pulmonary embolism is the dominant pathology in the patient*s
  • presentation and qualifying cardiorespiratory parameters.
  • 3) Temperature above 39oC / 102.2oF
  • 4) Logistical reasons limiting the rapid availability of interventional
  • procedures to treat
  • acute PE (e.g., during the outbreak of an epidemic)
  • 5) Index PE symptom duration > 14 days
  • 6) Active bleeding
  • 7) History of intracranial or intraocular bleeding at any time
  • 8) Stroke or transient ischemic attack within the past 6 months, or previous
  • stroke at any
  • time if associated with permanent disability
  • 9) Central nervous system neoplasm, or metastatic cancer
  • 10) Major neurologic, ophthalmologic, abdominal, cardiac, thoracic, vascular or
  • surgery or trauma (including syncope-associated with head strike or skeletal
  • within the past 3 weeks
  • 11) Platelet count < 100 x 109 x L-1
  • 12) Patients who have received a once-daily therapeutic dose of LMWH or a
  • therapeutic dose
  • of fondaparinux within 24 hours prior to randomization
  • 13) Patients who have received one of the direct oral anticoagulants apixaban
  • or rivaroxaban
  • within 12 hours prior to randomization
  • 14) Patients who have received one of the direct oral anticoagulants dabigatran
  • or edoxaban
  • for the index PE episode, as these drugs are not approved for patients who have
  • received heparin for at least 5 days
  • 15) Administration of a thrombolytic agent or a glycoprotein IIb/IIIa receptor
  • during the current hospital stay and/or within 30 days, for any reason
  • 16) Chronic treatment with antiplatelet agents other than low-dose
  • acetylsalicylic acid or
  • clopidogrel 75 mg once daily (but not both). Dual antiplatelet therapy is
  • 17) Chronic treatment with a direct oral anticoagulant (apixaban, dabigatran,
